33 But the crucifiers who corrupted the soldiers with a bribe, they perhaps said concerning Paul—“The disciples have bribed him with a bribe; therefore he associates with the disciples.” For those who by the giving of a bribe strove that the resurrection of our Lord might not be preached, slandered Paul with the name of a bribe, that his revelation might not be believed. Therefore the voice astonished him, and the light blinded him, that his astonishment might pacify his violence, and his blindness might put to shame his slanderers. For the voice astounded his hearing in this, that it said meekly to him—(Saul, why do you persecute Me?): and the light blinded his sight, that when the slanderers should have said that he had received a bribe, and thereby was suborned to lie, his blindness which had been brought about by that light might confute them, showing that it was through it that he had been driven to speak what was true. So that those who supposed that his hands had received a bribe, and that because of it his lips lied, might know that his eyes had given up their light and because of this his lips proclaimed the truth. But again for another reason the meek voice accompanied the overpowering light; namely, that as it were from meekness unto exaltation our Lord might produce help for the persecutor; in like manner as also all His helps were produced, from lowliness unto greatness. For our Lord's meekness continued from the womb to the tomb. And observe that greatness comes close upon His lowliness, and exaltation on His meekness. For whereas His greatness was observed in various things, His Divinity was revealed by glorious signs; that it might be known that the One Who stood among them, was not one but two. For His nature is not humble nature alone, nor is it an exalted nature alone; but there are two natures that are mingled, the one with the other; the exalted and the humble.
Therefore these two natures show forth their qualities; so that by the quality of each of the two, mankind might distinguish between the two; that it might not be supposed that He was merely one—He Who was two by commingling: but that it might be known that He was two in respect of the blending, though He was one in respect of His Being. These things our Lord, through His humility and exaltation, taught to Paul also in the way to Damascus.
